The useful life of a certain piece of equipment is determined by the following formula: u =(8d)/h^2, where u is the useful life
Anastaziya [24]

Answer:

E. 800%

Step-by-step explanation:

Since,

u = 8d/h²      __________ eqn (1)

Now, density (d) is doubled and usage (h) is halved.

Hence the new life (u'), becomes:

u' = 8(2d)/(0.5h)²

u' = 8(8d/h²)

using eqn (1), we get:

u' = 8u

In percentage,

u' = 800% of u

In words, the percentage increase in useful life of the equipment is <u>800%</u>.

Someone please help me with this question
kupik [55]

Answer:

see below

Step-by-step explanation:

(w+14)/2 = 10

Multiply each side by 2

(w+14)/2  *2 = 10*2

w+14 = 20

Subtract 14 from each side

w+14-14 = 20-14

w = 6

the population of a city is 25,000. if the number of males is 240 more than the number of females, how many males and females ar
muminat
M=f+240

m+f=25000, using m from above in this equation gives you:

f+240+f=25000  combine like terms on left side

2f+240=25000  subtract 240 from both sides

2f=24760  divide both sides by 2

f=12380, and since m=f+240

m=12620

So there are 12620 males and 12380 females in the city.

Solve for the value of v.
Mashcka [7]

Answer:

9

So...

(8v +3) +105 = 180

8v + 3 + 105 = 180

8v = 180 - 108

V = 72/8

= 9
